LONDON, England - January 26, 2009 – Prime Minister Gordon Brown said Monday the financial crisis must not be an excuse to retreat into protectionism and instead be viewed as the "difficult birth-pangs of a new global order".

In a speech, he will urge countries to avoid "muddling through as pessimists" and "make the necessary adjustment to a better future and setting the new rules for this new global order", according to his office.

Official data confirmed Friday that Britain is in recession. Days earlier, the government unveiled a new package of measures to help the flow of credit in the economy, but Brown has argued global action is needed for a quick recovery.

He will warn Monday that the crisis has given the world a choice: "We could allow this crisis to start a retreat from globalization.

"As some want, we could close our markets - for capital, financial services, trade and for labor - and therefore reduce the risks of globalization.

"But that would reduce global growth, deny us the benefits of global trade and confine millions to global poverty.

"Or we could view the threats and challenges we face today as the difficult birth-pangs of a new global order - and our task now as nothing less than making the transition through a new internationalism to the benefits of an expanding global society."

Britain is hosting a summit of the Group of 20 (G20) advanced and developing nations in London on April 2, and Brown has held preparatory talks with the French and German leaders, as well as new U.S. President Barack Obama.

He will meet with Chinese Prime Minister Wen Jiabao, South Korean Prime Minister Han Seung-Soo and Japanese premier Taro Aso, as well as World Bank chief Robert Zoellick at the World Economic Forum (WEF) in Davos this week.

Brown's Downing Street office said he would discuss with them "how we can best work internationally on financial reform, economic expansion and the creation of jobs in new sectors such as the environment."
